FIELD OF TECHNOLOGY

The present disclosure relates to the technical field of electronic cigarettes/atomizers or medical aids, and more particularly, relates to an electronic atomizer (cartridge) with a child-resistant lock and an exhaust function.

BACKGROUND

An electronic atomization apparatus (electronic cigarette cartridge) mainly includes a mouthpiece and a reservoir. The reservoir mainly includes a centerpost, an oil tank and a 510 thread. The mouthpiece, the centerpost and the oil tank of the reservoir need to be in sealed connecttion after atomized liquid is injected into the oil tank, so as to prevent the atomized liquid from leaking out from the reservior.

To make sure that the connection is reliable, at present, the connection between the mouthpiece and the reservior of the electronic atomization apparatus on the market is achieved mainly through the following two connection methods:

-   (1) an upper end of the centerpost is machined (by direct machining     or by reversely upsetting a step on the top) or riveted to form an     annular barb, and then hooks disposed on the mouthpiece are hooked     to the barb of the centerpost for connection; and -   (2) the upper end of the centerpost is machined (by direct machining     or by reversely upsetting and then tapping the top) or riveted to     form an external thread, and then an internal thread disposed on the     mouthpiece is screwed to the external thread of the centerpost for     connection.

In the above connection structure, the mouthpiece needs to be equipped with the hook or thread structure for connection to the centerpost. In practical applications, a plurality of parts are required to machine the multi-petal hooks or thread on the mouthpiece. In addition, during a stretching process, the top of the centerpost needs to be reversely upset to form a thicker section. During a machining process, the top also needs to be machined to form a thicker section for machining a limiting step or thread. Or, the top of the centerpost needs to be riveted to form limiting buckles or threaded buckles. As a result, the structure is complicated, and the assembly cost and quality control requirements are high.

The solution has the following beneficial effects:

1. The mouthpiece and the centerpost are in clamped connection through the child-resistant lock, and the child-resistant lock has an elastic function. As a result, compared with a solution of machining threads or assembling a hook part, the one-part mouthpiece of the present disclosure does not need extra assembly parts, thereby reducing the number of accessories and assembly costs of the electronic atomizer of the present disclosure.

2. The centerpost and the child-resistant lock can be in clamped connection in advance, and no accessory is required in the mouthpiece. In the subsequent assembly process of the child-resistant lock and the mouthpiece, only sealing silicone needs to be added for gap sealing between the mouthpiece and the oil tank and gap sealing between the mouthpiece and the centerpost. In this way, compared with the prior art, the quality risk generated during the assembly process of the electronic atomizer of the present disclosure is greatly reduced.

3. The mouthpiece and the centerpost are in clamped connection through the child-resistant lock, and the child-resistant lock can be made of material with high elasticity, such that damage to internal structures of the mouthpiece and the centerpost caused by direct clamped connection between the mouthpiece and the centerpost made of hard material can be effectively avoided.

4. The plurality of elastic arms are disposed at the upper section of the child-resistant lock, the elastic gaps are provided between the elastic arms, and when the elastic hooks at the upper ends of the elastic arms are in contact with the mouthpiece hooks disposed on the inner wall of the hollow cavity of the mouthpiece, the elastic arms can be bent inward due to the elastic gaps. Due to bending elasticity of the elastic arms, damage to the elastic hooks and the mouthpiece hooks caused by hard contact can be effectively reduced and avoided.

5. Compared with a centerpost with a thread or an annular barb at an upper end, the centerpost of the present disclosure is more simple to process. In addition, the centerpost of the electronic atomizer is generally made of metal material, a heating wire of the electronic atomizer is disposed at a lower end of the centerpost, and heat generated by the heating wire of the electronic atomizer can be conducted upward through the centerpost. Thus, compared with a process of directly connecting the centerpost to the mouthpiece in the prior art, the child-resistant lock of the present disclosure has an effect of heat insulation between the centerpost and the mouthpiece during use.

DESCRIPTION OF THE EMBODIMENTS

In order to have a clearer understanding of the technical features, objects and effects of the present disclosure, the specific implementations of the present disclosure will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 5 , in a first embodiment of an electronic atomizer (cartridge) with a child-resistant lock and an exhaust function according to the present disclosure, the electronic atomizer with the child-resistant lock and the exhaust function includes a mouthpiece 1 and a reservoir. The reservior includes a centerpost 2 of a hollow structure, and an oil tank 3 used for storing atomized liquid. The mouthpiece 1 and the centerpost 2 are connected through the child-resistant lock 4 disposed in hollow cavities of the mouthpiece and the centerpost.

The connection structure and method of the child-resistant lock 4 and the mouthpiece 1 of the atomizer of the present disclosure will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 to FIG. 5 , the child-resistant lock 4 is of a vertically through cavity structure, an upper end of the child-resistant lock is connected to the mouthpiece 1, and a lower end of the child-resistant lock is connected to the centerpost 2. A plurality of elastic arms 4 a are disposed at an upper section of the child-resistant lock 4, elastic hooks 4 b are disposed at upper ends of the elastic arms 4 a, and elastic gaps 4 c are provided between the elastic arms 4 a.

Mouthpiece hooks 1 b are disposed on an inner wall 1 a of the hollow cavity of the mouthpiece 1. The upper section of the child-resistant lock 4 extends into the hollow cavity of the mouthpiece 1, and the elastic hooks 4 b on the elastic arms 4 a are hooked on the mouthpiece hooks 1 b on the inner wall 1 a of the hollow cavity of the mouthpiece 1, so as to achieve clamped connection between the child-resistant lock 4 and the mouthpiece 1.

The mouthpiece 1 is rotatable by 360° along an axis of the reservior (corresponding to the centerpost 2 or the oil tank 3), such that the mouthpiece 1 can be aligned with Logo printed on the oil tank conveniently.

Specifically, the connection between the mouthpiece 1 and the child-resistant lock 4 is as shown in 2-2 in FIG. 2 . The child-resistant lock 4 is fixedly connected to the centerpost 2 in advance, the mouthpiece 1 is pressed down into a cavity of the oil tank 3, and when the mouthpiece 1 moves downward, the elastic hooks 4 b of the elastic arms 4 a of the child-resistant lock 4 are squeezed by inner walls of the mouthpiece hooks 1 b of the mouthpiece 1, such that the elastic arms 4 a are bent inward, and the elastic gaps 4 c between the elastic arms 4 a become smaller. After the mouthpiece 1 moves downward to be in complete contact with the oil tank 3, the elastic hooks 4 b disposed on the elastic arms 4 a of the child-resistant lock 4 are completely hooked at upper ends of the mouthpiece hooks 1 b of the mouthpiece 1, and the elastic arms 4 a rebound outward to an initial state.

The mouthpiece 1 and the oil tank 3 are in airtight connection through a sealing ring 51, and the mouthpiece 1 and the centerpost 2 are in airtight connection through a sealing collar 52. Further, as shown in FIGS. 2-3 and FIGS. 2-4 , connection sealing between the mouthpiece 1 and the oil tank 3 and sealing between the mouthpiece 1 and the centerpost 2 may also be achieved at the same time through a part seal 5.

Through the one-part mouthpiece, the material cost and assembly cost can be greatly reduced, the risk of quality control in the assembly process can be reduced, and production efficiency can be improved.

Further, as shown in FIG. 3 , the mouthpiece 1 may be configured as a split structure including a mouthpiece frame 11 and a lining 12, the mouthpiece frame 11 and the lining 12 are in sealed and firm connection, and the mouthpiece hooks 1 b are disposed on an inner wall 1 a of a hollow cavity of the lining 12. The mouthpiece frame 11 and the lining 12 may be in firm and sealed connection through force fit and riveting, or through adhesion with a sealant.

That is, the mouthpiece 1 is pressed along the centerpost 2, and the action of mounting a mouthpiece cover may be completed through buckled connection of the mouthpiece hooks 1 b and the body (formed by the centerpost 2 and the oil tank 3).

As the mouthpiece 1 is split, a wall thickness of the single mouthpiece 1 can be further reduced, and as the mouthpiece hooks 1 b are disposed on the inner wall 1 a of the hollow cavity of the lining 12, the mouthpiece 1 can be prevented from being entirely scrapped after being formed due to defects of the mouthpiece hooks 1 b.

Connection between the lining 12 and the child-resistant lock 4 is as shown in 3-2 in FIG. 3 .

The technical solution is to prevent the situation that in the connection process of the mouthpiece 1 and the child-resistant lock 4, the child-resistant lock 4 is overloaded when moving upward in the hollow cavity of the mouthpiece 1, and thus cannot be firmly clamped and shakes up and down.

In some implementations, as shown in FIG. 4 and FIG. 5 , a limiting convex ring 4 d is disposed at lower ends of the elastic arms 4 a of the child-resistant lock 4, and a limiting boss 1 c is disposed on the inner wall 1 a of the hollow cavity of the mouthpiece 1 or the lining 12. After the mouthpiece 1 and the child-resistant lock 4 are connected, an upper end face of the limiting convex ring 4 d of the child-resistant lock 4 is in contact with a lower end face of the limiting boss 1 c of the mouthpiece 1 or the lining 12. The mouthpiece 1 and the child-resistant lock 4 are connected through clamping of the mouthpiece hooks 1 b and the elastic hooks 4 b, and limiting fit of the limiting boss 1 c and the limiting convex ring 4 d. Connection between the child-resistant lock 4 with the limiting convex ring 4 d and the mouthpiece 1 with the limiting boss 1 c is as shown in 4-2 in FIG. 4 , and connection between the child-resistant lock 4 with the limiting convex ring 4 d and the lining 12 with the limiting boss 1 c is as shown in 5-2 in FIG. 5 .

Configuration form 3: as shown in FIG. 7 , the mouthpiece hooks 1 b on the inner wall 1 a of the hollow cavity of the mouthpiece 1 or the inner wall 1 a of the hollow cavity of the lining 12 are configured as a convex ring hook 1 b 3 riveted on the inner wall 1 a of the hollow cavity of the mouthpiece 1 or the inner wall 1 a of the hollow cavity of the lining 12.
